Construction structure and process for controlling slope of underwater reef explosion slope through pre-splitting blasting
The invention relates to the technical field of offshore construction, in particular to a construction structure and process for controlling the slope of an underwater reef explosion slope through pre-splitting blasting. The construction process for controlling the slope of the underwater reef explosion slope through pre-splitting blasting comprises the steps of main blast hole construction, pre-splitting hole construction, wiring operation, wiring protection and detonation. By means of the invention, the slope of the underwater reef explosion foundation trench slope can be effectively controlled; when the underwater foundation trench slope is constructed, the distance between the pre-splitting holes and the bottom edge line of the slope is controlled, so that the integrity of a slope rock body can be achieved after blasting, and the slope of the slope required by design can be achieved; the construction operation is simple and convenient; and the reef blasting amount, the foundation backfill amount and the construction cost can be reduced.
本发明涉及海上施工技术领域，特别涉及一种预裂爆破控制水下炸礁边坡坡度的施工结构与工艺。该工艺包括主炮孔施工、预裂孔施工、连线作业、连线保护、起爆。本发明可有效控制水下炸礁基槽边坡坡度，当进行水下基槽边坡施工时，通过控制预裂孔距离边坡底边线的距离，使爆后既能达到边坡岩体的完整，又能达到设计要求的边坡坡度，施工操作简便，可减少炸礁方量、基础回填方量、降低施工成本。
